NCT ID NCT02286557
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times
Summary
This study tested whether methylphenidate, a drug used for ADHD, can reduce the mental exhaustion that affects up to 95% of people with multiple sclerosis. Thirty-six adults with MS took both the drug and a placebo for four weeks each, without knowing which they were getting. The goal was to see if methylphenidate improves fatigue and thinking speed.
